This Monster Wants to Eat Me

According to an ancient legend, mermaid's flesh can grant immortality if eaten. 500 years ago, Yuta unknowingly ate a piece of mermaid's flesh. For centuries, he travels across Japan, hoping to find a mermaid, thinking she may be able to make him a normal human again. When he finally finds one, he discovers that she and her companions have been raising a girl to be their food so they can eat her and take on her youthful looks. That is how mermaids stay young. Yuta kills the mermaids and rescues her, but she has already eaten some of the mermaid's flesh. Although he had to kill the mermaids, Yuta isn't too disappointed. Yuta's once lonely existence is now over, as he has found a companion in Mana. And Mana, who had been trapped in a small hut her whole life, finds delight in even the simplest of things. Together, Yuta and Mana attempt to seek out more mermaids, trying to become normal humans again.

At the mysterious orphanage where Sheena lives, death is nothing new to its residents—girls who no longer have families of their own, who are raised as weapons of war, taught to kill and take the lives of others without batting an eye. Everyone, that is, except Sheena, who wishes for nothing more than the growing conflict around her to end. On the night of her roommate's death, Sheena meets a strange girl covered in blood, who smiles despite the turmoil surrounding them. The next day, the girl appears as a new student in Sheena's class and introduces herself as Mimi. Initially thought to be a school myth, there are now whispers in the orphanage's halls that Mimi is their secret weapon—an immortal who cannot die. When Mimi is later assigned as Sheena's new roommate, Sheena's world grows even more complicated when she begins living with someone who loves and welcomes death, when all Sheena wants to do is stop it…
